Arrangement of gas-retort benches

ARRANGEMENT OF GAS-RETORT BENCI-IES.

Specification of Letters Patent No. 15,010, dated June 3, 1856.

T 0 aZZ whom 2'?? may concern:

Be it known that I, JOHN G. Hock, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Gas-Retort Benches; and I dohereby declare that the following is a. full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l, is a transverse vertical section of a bench of five retorts constructed according to my invention, taken in the line a', of Figs. 2 and 3. Fig. 2, is a horizontal section of the same, in the line y, y, of Fig. 1, showing the arrangement of the flues for heating the upperretort. Fig. 3, is a horizontal section, in the line c, o, of Fig. l, showing the arrangement of flues under the lowest retorts.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in a novel arrangement of iues in a bench of five retorts whereby I am enabled to bring the flame and heated products of combustion into action on the retorts in such a manner as to heat them individually in all their parts and collectively, with a greater degree of uniformity than they can be in the common bench of five retorts, thereby increasing the durability of the retorts, and whereby I at the same time effect a considerable saving in fuel.

To enable others skilled in the art to make and use my invention, I will proceed to describe the construction and operation.

A, A, A1, A1, A2, are the retorts which are arranged relatively to each other substantially in the same form (shown in Fig. l), as in the bench of live retorts commonly used.

B, is the fireplace which is at the center of the bottom of the bench and some distance below the lowest retorts, A, A, as shown in Fig. l. This fire place extends little more than half the length of the bench, as shown in Fig. 3.

a, a, (Figs. l and 3), are horizontal flues leading from each side of the upper part of the fire place under the two lower retorts, A, A, which, as well as all the other retorts, have their entire length resting upon tiles, Z), b, which protect their bottoms from the too strong action of the flame from the re. The flues, a., a, communicate with other flues, c, eZ, and e, e, the latter of which communicate with a central iue, f, in rear of the fireplace.

g, (Figs. 2 and 3) is an upright flue leading from the rear of the flue, f, to a horizontal flue, ZL, which passes through the center of the bench under the top retort, A2.

2'., (Figs. 1 and 2) is a short flue descending from the front end of the flue, Zz, and having two branches, j, y', leading to two wide horizontal iues, 7c, 7c, in which the bottom retorts, A, A, are placed.

Z, Z, (Fig. 2) are openings at the rear of the Hues, 7c, le, leading into the open space, C, in hich are placed the retorts, A1, A1, and A2.

D, is the chimney leading out of the forward part of the space, C.

The flame and heated products of combustion from the ire pass through the fiues, a, a, and circulate through the fiues, c, CZ, e, e, under the lower retorts,.A, A, thus heating` the bottoms thereof. They then enter the flue, f, and from thence pass up the flue, g, into the flue, la., under the top retort, A2, and pass through the latter flue in a forward direction, and escape therefrom down the flue, Z, and through the flues, y', j, into the wide flues, 7c, c, through which they pass in a backward direction to heat the sides and upper parts of the retorts, A, A, and bottoms of the retorts, A1, A1. They then pass in a forward direction through the openings, Z, Z, into the space, C, C, to heat the sides and upper parts of the retort-s, A1, A1, and A2, and finally escape to the chimney, D.

By the above arrangement, it will be seen, that flame is prevented striking directly upon any one part of any of the retorts, as it does when the bench is constructed in the usual manner, which is so destructive to retorts.

lVhat I claim as my invent-ion, and desire to secure by Letters Patent, is,

The within described arrangement of t-he fiues by which the flame and heated products of combustion are caused to pass first under the bottom retorts, A, A, next under the top retort, A2, then under the retorts, A1,A1, and over A, A, and finally over A1, A1, and A2, as herein set forth.

JOHN G. HOOK.
